Hummingbird beat their wings many times per second which equation relates the number of beats per second (a) to the number of wing per minute (b) A. b=a+60
B. b=60/a
C. b=60a
D=a/60

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
